# This script sets up a few customizations particular to Bio-Linux
# that can't be put into packages.  On first boot (after
# installation) this script should execute once and then delete itself,
# or at least unhook itself from /etc/rc?.d.  Maybe there is a way to 
# make this a post-install hook for Ubiquity??

# This line is dynamic (generated by the build script) so it may change
# after the date at the top of the file.
# Erm - the file should be there already, right?
